Falsely positive heparin-induced thrombocytopenia antibody testing in severe hyperbilirubinemia.

Heparin-induced thrombocytopenia (HIT) is a life-threatening pathologic reaction to heparin-based products. Diagnosis of this condition can be confounded by other comorbidities or by acute illness-oftentimes presenting challenging clinical dilemmas, particularly in critically ill patients. A 67-year-old woman was admitted with liver failure and severe hyperbilirubinemia.

Coupling between motor cortex and striatum increases during sleep over long-term skill learning.

The strength of cortical connectivity to the striatum influences the balance between behavioral variability and stability. Learning to consistently produce a skilled action requires plasticity in corticostriatal connectivity associated with repeated training of the action. However, it remains unknown whether such corticostriatal plasticity occurs during training itself or 'offline' during time away from training, such as sleep.

High density carbon fiber arrays for chronic electrophysiology, fast scan cyclic voltammetry, and correlative anatomy.

Objective: Multimodal measurements at the neuronal level allow for detailed insight into local circuit function. However, most behavioral studies focus on one or two modalities and are generally limited by the available technology.

Approach: Here, we show a combined approach of electrophysiology recordings, chemical sensing, and histological localization of the electrode tips within tissue.

Impact of pre-OP independence in patients with limited brain metastases on long-term survival.

Background: Brain metastasis represents a major complication with a significantly shorter overall survival of many oncological diseases, in particular of lung cancer, breast cancer and malignant melanoma patients. However, despite the poor prognosis, sometimes clinical decision-making, between on the one hand not to harm the patient and on the other hand not withholding a potential therapeutic option, is very challenging. Thus the aim of this retrospective study was to compare various scores, including scores for activities of daily living (ADL) before resection of brain metastases and to analyse their impact on survival.
